The definition of a low-carb diet ranges around 75 or fewer grams of net carbs daily. The ketogenic diet or very low carb is generally defined as not consuming more than 20 grams of net carbs per day. Many people find that strictly limiting their carb intake makes it easier to lose weight and keep weight off. For those concerned about their blood sugar, cutting way back on carbohydrates can be helpful to help lower blood sugar issues as well as triglyceride numbers and other health markers. This means limiting the number of sugars and starches, including all sweeteners, pasta, potatoes, starch-based flours, and most fruits.
